Grade 12 vectors: velocity? Mary leaves a dock, paddling her canoe at 3 m/s. She heads downstream at an angle of 30 degrees to the current, which is flowing at 4 m/s. How far downstream does Mary travel in 10s? Answer: about 66m How do you solve this? I don't know how to draw the diagram...

we know magnitude and direction of both vectors right?
hey amistre got ya another one above this q when ur done mate
we also have a scalar of 10

scale the vectors then add them 30 degrees = has a unit vector of so at 3 = <3sqrt(3),3> 10<3sqrt(3),3> + 10<0,4> = <30sqrt(3),30> < 0 ,40> --------------- <30sqrt(3), 70> right?
the magnitude of this vector should be the distance traveled
sqrt(70^2 + 30sqrt(3)^2) sqrt(4900 + 900(3)) sqrt(7600) right?
87.1779... to find the distance travled downstream tho, we take this distance and multiply it by the cos(30) to get a vector projection
what i come up with is: 75.49 but then I could be wrong
did you typo the question?
No, there's no typo. But thanks amistre! :)
ok i have a Q, how far did she paddle on the horizon before she went to the 30 degree angels downstream, some data is missing i believe
